Main Question or Discussion Point
I would like to know views on the force required to pull a cylindrical cover.
A plastic shade cover is almost 290 ft in length and 150 ft in breadth. It is wrapped around a cylindrical wooden rod which is at a height of 7 ft from the ground. The cover is pulled by plastic ropes to the right to its complete length of 290 ft. Consider the thickness of plastic cover to be 10 mm and density of plastic as 850 kg/m3. The ropes are pulled by 7 people towards right.
How much force is required to pull the cover completely to the right?
Should the force be equal on all the ropes?
Please give views on an efficient pulley system to help the 7 people.
